Syntax

QUANTITY ( expression )


Implemented in iMath since version 2.2.0 or earlier.

Explanation

Try to find a quantity for the expression from any equations defined previously in the document. Gives an error if the expression does not evaluate to a quantity.

All numerical values will be converted to floating point numbers. If you do not want this, use VAL instead.


Example

EQDEF a = 3 x

EQDEF b = 2 x

EQDEF x = 7 %metre

EXDEF QUANTITY(a + b)

This will output 35 "m".
